Hii Abhishek!
Stressing at this point of time will not help you perform well in exams. I know it's very obvious to stress and you can't help it. But, the thing which you can do is, try to be calm, meditate, exercise, eat healthy and sleep well in order to maintain a good health and help you relax and releive the stress. You need to focus on your strong points at this point of time and revise as much as you can. Make small pocket notes of the topics you are weak in and revise and learn them every day. Practice as much questions and problems as you can preferably previous year question papers. This will help you get an idea of the type of questions asked in the exam. Most importantly, keep a check on your health. Relax. Everything is going to be fine. You just need to concentrate on your studies now. Hope you understand.
All the best!
